One should also beware of Forgetfulness, which neutralizes ranged units, Teleport, which is Exactly What It Says on the Tin, and Steal All Enchantments, which removes all status buffs from the enemy and gives them to your own army. The aforementioned Blind and Berserk? Level 4 Order spells, but dwarfed by the level 5 Hypnotize, the granddaddy of mind control spells. All you need to do is stack mass Haste on top of that to complete the Humiliation Conga. Combine the mass version (which targets all enemy units) with the above three spells and your enemies are sitting ducks. Even the 1st level spell Slow, which reduces the rate enemy units' turns come up, remains effective up to the late-game.

V's dark magic in general is pretty damn powerful.

Blind and Berserk pretty much ruined the opposition's day in III and IV as well.

Careful use of these three spells will cripple even the strongest armies.

The Puppetmaster, Blind, and Frenzy spells in V (yes, V has quite a few gamebreakers).

For every creature a ghost kills it adds one ghost to the stack, and with a reasonably intelligent player controlling them, it's easy to have a stack of 100+ ghosts within the first week - and because of the way the killing things equals more ghosts, an army with ghosts will snowball into invincibility through numbers within a month. Use the map editor to add ghosts into your army manually and you'll see why.

Ghosts in II are the one creature in the game where there is no way during standard gameplay to recruit them into your army.

They are even harder to get than genies, though. Usually chances are calculated by comparing the total hitpoints of the involved stacks, but death knights always have a 25% chance.

Death knights take a similar role in V.

Although, the vampire's power might be just due to the rather bizarre way to balance the Necropolis, where outstandingly strong creatures(vampires, death knights, liches and to some extent skeletons) are 'balanced out' with laughably weak ones (walking dead and wights). The upgraded versions in the third and fifth game as well as the vampire in the fourth game combine decent stats for their tier, the ability to fly/teleport on the battlefield, no enemy retaliation, and the ability to heal and revive their numbers when attacking living units.

The Necropolis' vampire in every game.

They're extremely fast and powerful, boasting the highest stats in the game and the ability to resurrect other units.

The Castle town's angel and archangel in III.

This is only somewhat mitigated by the fact that they can't fly, they only have 50% magic immunity instead of the Black Dragons' 100% (though this means that their stats can be buffed even further by spells), and the fact that they usually can't be recruited on maps by any hero. These guys have monstrous amounts of health (more than twice as much as their closest competitor, the Black Dragon), as well as disgusting amounts of damage capabilities and the standard dragon breath attack, which can hit two stacks of troops at once.

IV continues the trend, especially with the expansion-exclusive Megadragon.

Usually falls under Awesome, but Impractical due to the staggering cost, however. Its special ability is to scare its enemies shitless, preventing them from taking any action for a turn, has by FAR the highest stats in the game, except speed which is still among the highest. How powerful? The strongest one, the azure dragon, costs 30000 gold and 20 mercury to recruit from its nest. Each is in a tier of their own and they are obscenely powerful.

Lampshaded in one of the random rumors you can hear at the tavern: 'A Black Dragon will take out a Titan any day of the week.' The third game's Armageddon's Blade expansion introduces four neutral dragon units. The dragons' dominance continued in Heroes II, though the titans did provide some resistance, though some speculate that it's not enough. Any warlock who can stock enough treasure to support them and have a secure access to a sulfur mine can storm his way through any other faction's armies without too much difficulty.

The dragons of the first game are much stronger than any of the other unique creatures of the other factions.
